Worrying about weird winters
Winter is a key determinant of biological processes in temperate, alpine, and polar environments. Winters are changing, yet we currently lack the knowledge to adequately predict the impacts of climate change on winter biology, or to link winter conditions to the growing-season performance of most organisms.
متن کاملAre winters getting warmer?
We examine whether any trends in monthly temperatures are the same through-out the year for various lengthy series. The data concern the world, the northern and southern hemispheres, and about three centuries of data for the United Kingdom and the Netherlands. For the empirical exercise, we rely on new and accurate tests which have been recently developed. These tests do not have standard distr...

متن کاملGeology of the Icy Satellites
In the last 25 years, the explorations of the Voyager and Galileo missions have resulted in an entirely new view of the icy worlds orbiting the giant outer planets. These objects show a huge diversity in their characteristics, resulting from their formation histories, internal processes and interactions with their space environments. This paper will review the current state of knowledge about t...
متن کاملMicrobial Habitability of Icy Worlds
F or most of Earth’s history, life was microscopic and, even today, microorganisms dominate the planet. Hence, we believe that, if life exists beyond Earth, it likely started as microorganisms and may remain at this stage. Much of contemporary astrobiological research focuses on the metabolic potential of microorganisms and their ability to inhabit extreme environments. The search for life beyo...
